2018 Audi A6 2.0L Diesel · SC67 HSX

This 2018 Audi A6 presents a broadly clean MOT record across its testing life, with no recorded failures and a steady run of pass certificates, most recently on 18 August 2026 where it was awarded a clean pass with only minor cosmetic advisories concerning deterioration of the front and rear registration plates. Across the four documented tests there is no escalation of concern; the only advisories that have recurred are the cosmetic plate deterioration noted this year, and a pattern of child seats preventing full inspection of the rear adult belts, which is a non-mechanical observation reflecting how the car has been used rather than any underlying defect. The substantive mechanical advisories have actually tapered off over time, with the rear tyre wear issues recorded in 2022 and 2024 not repeating on the latest test, suggesting that consumable replacement has been attended to as the mileage has accumulated. With 119,698 miles recorded over roughly eight years, this A6 is running at approximately 14,962 miles per year, which is firmly on the higher side for its age and well above the average for an executive saloon of this type. There are no extended gaps in the MOT testing record, so the annual mileage accumulation appears consistent rather than indicative of long periods off the road followed by catch-up use. High annual mileage of this nature places greater cumulative load on braking components, suspension bushes and joints, drivetrain mounts, and dual-clutch or automatic transmission fluid and mechatronics, so while the car has remained legally roadworthy, the mechanical inventory should be regarded as one that has been worked rather than lightly used. The advisories that have appeared over the testing history concentrate almost exclusively on the braking system and tyre wear on the 245/45 R18 fitment. Brake disc wear was flagged at both the nearside front and offside rear in 2022 and again in 2023, alongside a fluctuating nearside front service brake in 2023, which together suggest that the discs and pads have been working through their service life and have likely been replaced by now. Front tyres have been noted down to 2mm and 3mm on both nearside and offside positions, and rear tyres have likewise been recorded at 3mm on more than one occasion, indicating that the car has been consuming tyres at a rate consistent with its high annual mileage. The single structural advisory in 2024, a corroded and split centre exhaust sleeve clamp, is a localised exhaust mounting issue rather than a chassis integrity concern, but it is worth confirming that the exhaust is still securely located and not knocking under load. The persistent nearside front tyre wear noted across 2022 and 2023, particularly the edge wear pattern, is the one item that warrants specific attention. On a test drive, listen carefully for any clonking or knocking from the front suspension over uneven surfaces, as the combination of high mileage and repeated edge-tyre wear can indicate worn suspension bushes or droplinks. Feel for any vibration or pulsing through the brake pedal, which would suggest residual disc runout or a binding caliper following recent pad changes, and confirm the car pulls up in a straight line without steering deviation. Listen for any exhaust rattle or movement under acceleration that could indicate the sleeve clamp repair noted in 2024 has deteriorated, and inspect the underside of the rear exhaust section for further corrosion around the mounting points. Finally, check the current front and rear tyres for uneven shoulder wear across both axles, as the historic edge-wear pattern returning would suggest an underlying geometry or suspension component issue that the MOT advisory history has hinted at but not flagged as a failure.
